E60 / E61 (2004 - 2010) BMW 5-Series E60 Sedan was first seen in the Unites States in the fall of 2003 with a 2004 Model Year designation. The E61 wagon followed shortly there after. The E60/E61 5 series is now available as a 528i, 528xi, 535i, 535xi, 550i and a 535xi sports wagon! -- View the E60 Wiki

Hopefully somebody has dealt with the following issue. Somehow our TPS unit in the trunk was damaged by pooling water in the trunk of our 2008 528xi. We park the car in a garage at all times when we are home. The dealer said he had heard of water entering the trunk when driving in rain. The trunk "lifts up" to allow water under the seal? I am getting ready to turn in the car at the end of our lease and I would like to possibly get some evidence of this problem to prevent me from being charged.

Below is a thread that you may want to read in its entirety. You will gain insight and make your decision on how to deal with your issue. There are others but this is one of the longer running one dealing with your issue...

It is an easy fix. Order the TPM module online around $64 and replace it. It will take about 10 minutes at best . The dealer will tell you that it will cost around $600 to replace and to program. As long at the dealer knows your VIN numer you will not have to program it to your car. It is plug and play.

Thanks for all of your responses in advance.

My tire pressure monitor went out as well. I didn't realize that it was in the trunk. When I took it into the dealership, they told me that water sometimes leaks into the trunk, possibly from heavy rain, and causes it to short out. They replaced it with no questions asked as the car was under warranty. However, when they explained where the TPM was and that it had gotten wet, I knew immediately what had happened. The malfunction light went on when I started the car up one morning when I was on an out of town trip. Before starting the car that, I put our luggage in the trunk and noticed that the cooler we had used for drinks the prior day had tipped over spilling water into the trunk. I didn't connect the malfunctioning TPM with the water until the dealer mentioned the reason for the malfunction.

The dealer didn't ask me anything about water in the trunk and I didn't mention anything. It seems to me that BMW should have the TPM system protected better or, at the least, BMW should warn owners not to allow water in the trunk. Based upon what my dealer said, I don't think it uncommon for trunks to leak and damage the TPM.

Getting ready to replace mine. My wife had an "Accident" involving laundry detergent in the trunk. fried the TPM module.

Anyone have link or part number? Im finding one on BMW Directparts, but no part number and its $120...

Thanks if anyone knows

Im relocating my TPM module just behind the black plastic trim piece thats where the trunk latch is. It comes off with 3 screws and has room behind it. The locaiton BMW chose is ridiculous, and makes no sense, considering stuff spills in trunks.

I also see there is a computer module under the spare tire, in that same molded foam piece that the TPM sits in. Im moving that behind the left side trim piece. Its got Fiber Optic and antenna cabels going to it, and when unplugged the car wont even start, unlock, etc...not sure if its the main computer, but without it, No Running Car.

Once I get enough Posts I will take some pics and post.

Ive never seen any critical electrical components located like this in any vehicle. Its crazy..plus the units are not water tight, and the circuit boards are not epoxy coated.

Its clearly a major design oversight...the reason you go with luxury vehicle is so ya dont worry about dumb things like "Hey if I spill milk in my trunk, will it make my car not statt?"
HAHA Oh well, live and learn.

Plugged it in, went to the iDrive menu, selected to reprogram TPM, 5 minutes later it worked!! I did have to exit the iDrive TPM menu for the warning light on dash to go away, but other than that, its as simple as plugging it in and going thru the iDrive menu.

Hi
I am a new member and now a boost fanatic
Anyhow I have found everybody so helpful - GREAT FORUM
Any how I just took my Control Module out, cleaned the corrosion on the pins with alcohol, and let it dry out in the sun for the day, It fixed it.

I don't know if it would work for everyone, but might be worth a shot.

My leaking Cooler damaged by TPS unit as well. bought new from ebay and plugged in and worked great. This time, I wrapped plastic bag around entire unit so next time, even water goes in trunk my TPS is still safe.

Just relocate the modules to the side panels and avoid the issue completely .
